Amazon.com Larger Font Bookmarklet

I like to read book reviews in Amazon.com with iPhone.
Amazon.com show optimized pages for iPhone.
I think its font size is so small.
Then I made a bookmarklet.

Amazon.com larger font bookmarklet

You can view pages with larger font when you run this bookmarklet.

var e = document.getElementsByTagName('div');

var n = e.length;

for (var i = 0; i < n; i++) {

   e[i].style.fontSize = '14px';

}
